The best design of sofa is created with luxurious appearance. This sofa is very comfortable to sit and it is very strong out side and smooth inside. The sofa consists of two elements – hard outer shell and soft inner cushion. These elements make this sofa more perfect to put in the living room to enjoy the free time together with family. The outer shell protects the sofa from the outside world and the inner cushion provides comfort to its user(s). This sofa is very resistant from the collision. This sofa is very safe to play when you have many kids in your house. In a way the sofa “functions” similarly to the protective mechanism used by many species – armadillos, hedgehogs, sea shells, etc; it protects and provides comfort to the pearl that sits/lives inside. It is very suitable for taking a nap in this sofa and it is very enjoyable for watching TV with sitting in this sofa. Interesting feature of the design are the steep and extra-cushioned “armrests”, which could be used as additional backrests.
